Summary

X-linked agammaglobulinemia (X-LA) is a common inherited antibody deficiency caused by Bruton's tyrosine kinase (Btk) mutations. This review covers X-LA pathogenesis, diagnosis, and treatment, including immunoglobulin therapy and potential gene therapy.

Area of Science:

  • Immunology
  • Genetics

Context:

  • X-linked agammaglobulinemia (X-LA) is the most common inherited antibody deficiency.
  • First described by Bruton, its detailed pathogenesis is recently understood.

Purpose:

  • To review current literature on X-linked agammaglobulinemia (X-LA).
  • To provide updates on pathogenesis, diagnosis, and treatment of X-LA.

Summary:

  • X-LA results from over 400 mutations in Bruton's tyrosine kinase (Btk), impairing B cell maturation and immunoglobulin synthesis.
  • Clinical features include recurrent bacterial infections in boys with low B cells and immunoglobulin levels.
  • Btk's role in B cell maturation in bone marrow and spleen is suggested by animal models.

Impact:
